what are nucleotides ? explain it deeply
Answers
Answer:
Nucleotides are organic molecules that serve as the basic structural (monomer) units for DNA and RNA, which, as we know, are the building blocks responsible for all life on Earth. Each nucleotide contains a nitrogenous base, a five-carbon sugar, and at least one phosphate group.
Answer:
The Base-Sugar-Phosphate unit is called nucleotide. A nuckeotide contains all the three components of nucleic acids. The phosphate group is attached to one of the -OH groups of the sugar unit of nucleotides by an ester bond.
Nucleotides are the phosphate esters of nucleoside. A nucleotide can be described by the structure.
Nucleotides are named on the basis of sugar present in it. There are only two sugars present in the nucleic acids, hence the corresponding nucleotides are
- Sugar : Ribose / Deoxyribose
- Nucleotide : Ribonucleotide / Deoxyribonucleotide
